Question

Why do lipids make effective cell membranes in living cells?

-They bond with water so that the cells are aqueous.
-They form barriers so undesirable molecules cannot pass through the membranes.
-They help cells flush out excess water.
-They provide hormones that help cells reproduce.

Answer 1

They form barriers so the second option is right because lipids are hydrophobic meaning they don’t mix with water

Answer 2

The answer is the second option. Lipids make effective cell membranes in living cells because lipids (fats) are not soluble in water. This means that lipids and water do not mix... This lipid bilayer helps to protect the cell.
